| 摘要 |
The invention provides a molding method and molding apparatus, effective and cheap, for a surface fastener to be directly/indirectly bonded with/fit to an mounting object, capable of increasing the bonding strength or friction force regardless of the configuration of a bonding surface, wherein molten resin is discharged continuously from a resin extruding port of an extrusion die to a peripheral surface of a die wheel having hook piece forming cavities therein for forming hook pieces in the hook piece forming cavities while forming a flat base member at a gap between the extrusion die and the die wheel, the rear surface of a surface fastener without engaging elements is cooled by feeding refrigerant through a refrigerant passage formed in the extrusion die below the resin extruding port, surface sinks are formed in the entire rear surface for increasing bonding area, thereby increasing bonding strength and friction force. |
